After upgrading from 3.76 to 4.01.xx doubleclicking a mht-file Windows comes up with an error message ("...mht could not be opened...") which has to be clicked away, but nevertheless the mht-file is opened in IE (forced program). There is no error message if a mht-file is opened via the file menu of IE, or if the file is opened outside the sandbox. I cleared the contents of the sandbox, but that didn't help. I deleted the sandbox, and created a new one, no vail.

This only happens on my Windows XP system (WinXP Pro SP3 32-bit, IE8). Everything works fine on my Win64 Ultimate 64-bit, also with IE8.

It's the same "Windows cannot find ..." message I see when typing a URL into the Run box, taskbar Address Bar, etc. (IE default browser, if that matters), except in those cases the browser opens but stays blank.

.url shortcuts are too simple , and I never saw a problem with them, even when I first reported (I used Favorites from XP Start Menu). As I said:
